Legendary Fisherman: Part 1 - S2-E19
Revealing mistake: When Joey summons Garoozis, Mako says, "Nice try," and activates his face-down card, Torrential Tribute. Right before the face-down card is revealed, the cards he is holding in his hand can be seen, and they are all missing the illustrations. (00:14:12)
Duel Identity, Part II - S1-E30
Character mistake: Yugi mistakenly says if he doesn't get a monster out to defend himself Mai can attack him directly, which wouldn't be possible since the rules of Duel Monsters during the Duelist Kingdom arc forbade direct attacks on defenseless opponents. That rule wouldn't be implemented until the Battle City arc.
Mai Valentine: Hey! Cross on the green, not in between.
Duke Devlin, Raphael, Valon: Sorry, but we're being chased by a bunch of robed weirdos.
